Question

expand :
a) (3a-5b-c)
b)(u-2/3 v)^3
c)(3/2p+1)^3
pls put the answer as step by step

Answer 1

Answer:

Step-by-step explanation:  

To expand

a) (3a - 5b - c)

It can be expanded using algebraic identity

(a - b - c) = a + (-b) + (-c )

where,

a = 3a

b = (-5b)

c = ( -c)

So,

(3a - 5b - c) = (3a) + (-5b) + (-c)  

 is the answer
